Summary:
Two years older but nowhere near as talented as Damian, Daire was kicked out of the League of Assassins when she was eleven.
Now thirteen, she is out for revenge. Her mother delivered horrible news: the little brother she loved was slain by the Batman. In his final breaths, he asked his mother to find his sister, so she could take his place as heir.
Unwilling to kill before, Daire is now out for revenge. Her target: her brother's father.
Disclaimer: I only own the characters I make up. All else goes to their respective owners.
Warning: will have mild cussing, murder, fight scenes, blood, and some gore. This story also mention child abuse: mental, physical, emotional, and sexual. It might also have other triggers.
Other important information:
I'm pretty sure Damian is ten in Son of Batman. He's eleven in this story.
Damian and Daire are half siblings. Same mother; different fathers. They grew up together and are close.
Damian is the favorite/ protégé. Daire wasn't bad but not as talented as her grandfather and mother wanted her to be, making her the disappoint.
